leonid [27]

Answer:

$(1, -2)$

Step-by-step explanation:

What is the measure of angle A, in degrees?

juin [17]

96°.

Since sides AB and AC ane equal, that means that angle B is equal to angle C. The measurement of all the angles of a triangle always equals 180°, so if you add angles B and C, you should get 84° and then you should be able to find angle A. Subtract 84° from 180° and you should get 96°.
